At the end are all the scriptures in the New Testament related to Judas Iscariot. First we should note that these scriptures leave many unanswered questions about Judas. If God thought the answers to these questions were important, he would have revealed them to us.
This temptation sounds an awful lot like a temptation for Jesus to be what the Jews expected him to be. Then, there is Jesus’ response to Peter’s rebuke of Jesus predicting his death:
This shows that Peter expected Jesus to be the Messiah that the Jews expected. One that would overthrow Rome and conquer the world. Note also Jesus’ use of the term Satan here.
All we can say from Matt. 27:3–5 is that Judas changed his mind about the betrayal and we can only speculate why. It is reasonable that Judas also expected Jesus to be the Messiah matching Jewish tradition. Matt. 26:20–25 indicated that selfishness motivated Judas. Thus, he followed Jesus for what he could get out of it. Here we enter into speculation, but it’s not unreasonable to see that Judas saw Jesus’ miracles and knew he had the ability to be the traditional Jewish Messiah. Note John 18:6 shows that even the soldiers who came to arrest Jesus were terrified by Jesus’ reputation. Thus, Judas may well have thought Jesus’ arrest would force Jesus to demonstrate his power. When Jesus acted otherwise, Judas felt such sorrow for his actions that he took his life.
Then one of the twelve, whose name was Judas Iscariot, went to the chief priests and said, “What will you give me if I deliver him over to you?” And they paid him thirty pieces of silver. And from that moment he sought an opportunity to betray him. (Matt. 26:14–16, ESV)
When it was evening, he reclined at table with the twelve. And as they were eating, he said, “Truly, I say to you, one of you will betray me.” And they were very sorrowful and began to say to him one after another, “Is it I, Lord?” He answered, “He who has dipped his hand in the dish with me will betray me. The Son of Man goes as it is written of him, but woe to that man by whom the Son of Man is betrayed! It would have been better for that man if he had not been born.” Judas, who would betray him, answered, “Is it I, Rabbi?” He said to him, “You have said so.” (Matt. 26:20–25, ESV)
Then he came to the disciples and said to them, “Sleep and take your rest later on. See, the hour is at hand, and the Son of Man is betrayed into the hands of sinners. Rise, let us be going; see, my betrayer is at hand.” While he was still speaking, Judas came, one of the twelve, and with him a great crowd with swords and clubs, from the chief priests and the elders of the people. Now the betrayer had given them a sign, saying, “The one I will kiss is the man; seize him.” And he came up to Jesus at once and said, “Greetings, Rabbi!” And he kissed him. Jesus said to him, “Friend, do what you came to do.” Then they came up and laid hands on Jesus and seized him. (Matt 26:45–50, ESV)
Then when Judas, his betrayer, saw that Jesus was condemned, he changed his mind and brought back the thirty pieces of silver to the chief priests and the elders, saying, “I have sinned by betraying innocent blood.” They said, “What is that to us? See to it yourself.” And throwing down the pieces of silver into the temple, he departed, and he went and hanged himself. (Matt. 27:3–5, ESV)
Then Judas Iscariot, who was one of the twelve, went to the chief priests in order to betray him to them. 11 And when they heard it, they were glad and promised to give him money. And he sought an opportunity to betray him. (Mark 14:10–11, ESV)
And when it was evening, he came with the twelve. 18 And as they were reclining at table and eating, Jesus said, “Truly, I say to you, one of you will betray me, one who is eating with me.” 19 They began to be sorrowful and to say to him one after another, “Is it I?” 20 He said to them, “It is one of the twelve, one who is dipping bread into the dish with me. 21 For the Son of Man goes as it is written of him, but woe to that man by whom the Son of Man is betrayed! It would have been better for that man if he had not been born.” (Mark 14:17–21, ESV)
Rise, let us be going; see, my betrayer is at hand.” And immediately, while he was still speaking, Judas came, one of the twelve, and with him a crowd with swords and clubs, from the chief priests and the scribes and the elders. Now the betrayer had given them a sign, saying, “The one I will kiss is the man. Seize him and lead him away under guard.” And when he came, he went up to him at once and said, “Rabbi!” And he kissed him. And they laid hands on him and seized him. (Mark 14:42–46,ESV)
Then Satan entered into Judas called Iscariot, who was of the number of the twelve. He went away and conferred with the chief priests and officers how he might betray him to them. And they were glad, and agreed to give him money. So he consented and sought an opportunity to betray him to them in the absence of a crowd. (Luke 22:3–6, ESV)
But behold, the hand of him who betrays me is with me on the table. For the Son of Man goes as it has been determined, but woe to that man by whom he is betrayed!” And they began to question one another, which of them it could be who was going to do this. (Luke 22:21–23, ESV)
While he was still speaking, there came a crowd, and the man called Judas, one of the twelve, was leading them. He drew near to Jesus to kiss him, but Jesus said to him, “Judas, would you betray the Son of Man with a kiss?” (Luke 22:47–48, ESV)
Jesus answered them, “Did I not choose you, the twelve? And yet one of you is a devil.” He spoke of Judas the son of Simon Iscariot, for he, one of the twelve, was going to betray him. (John 6:70–71, ESV)
But Judas Iscariot, one of his disciples (he who was about to betray him), said, 5 “Why was this ointment not sold for three hundred denarii and given to the poor?” 6 He said this, not because he cared about the poor, but because he was a thief, and having charge of the moneybag he used to help himself to what was put into it. (John 12:4–6, ESV)
During supper, when the devil had already put it into the heart of Judas Iscariot, Simon’s son, to betray him, … For he knew who was to betray him; that was why he said, “Not all of you are clean.” (John 13:2,11)
After saying these things, Jesus was troubled in his spirit, and testified, “Truly, truly, I say to you, one of you will betray me.” The disciples looked at one another, uncertain of whom he spoke. One of his disciples, whom Jesus loved, was reclining at table at Jesus’ side, so Simon Peter motioned to him to ask Jesus of whom he was speaking. So that disciple, leaning back against Jesus, said to him, “Lord, who is it?” Jesus answered, “It is he to whom I will give this morsel of bread when I have dipped it.” So when he had dipped the morsel, he gave it to Judas, the son of Simon Iscariot. Then after he had taken the morsel, Satan entered into him. Jesus said to him, “What you are going to do, do quickly.” Now no one at the table knew why he said this to him. Some thought that, because Judas had the moneybag, Jesus was telling him, “Buy what we need for the feast,” or that he should give something to the poor. So, after receiving the morsel of bread, he immediately went out. And it was night. When he had gone out,… (John 13:21–31, ESV)
While I was with them, I kept them in your name, which you have given me. I have guarded them, and not one of them has been lost except the son of destruction, that the Scripture might be fulfilled. (John 17:12, ESV)
When Jesus had spoken these words, he went out with his disciples across the brook Kidron, where there was a garden, which he and his disciples entered. Now Judas, who betrayed him, also knew the place, for Jesus often met there with his disciples. So Judas, having procured a band of soldiers and some officers from the chief priests and the Pharisees, went there with lanterns and torches and weapons. Then Jesus, knowing all that would happen to him, came forward and said to them, “Whom do you seek?” They answered him, “Jesus of Nazareth.” Jesus said to them, “I am he.” Judas, who betrayed him, was standing with them. 6 When Jesus said to them, “I am he,” they drew back and fell to the ground. (John 18:1–6, ESV)
Brothers, the Scripture had to be fulfilled, which the Holy Spirit spoke beforehand by the mouth of David concerning Judas, who became a guide to those who arrested Jesus. For he was numbered among us and was allotted his share in this ministry.” (Now this man acquired a field with the reward of his wickedness, and falling headlong he burst open in the middle and all his bowels gushed out. And it became known to all the inhabitants of Jerusalem, so that the field was called in their own language Akeldama, that is, Field of Blood.) (Acts 1:16–19, ESV)
